Server DDR5 6400 ECC RDIMM kit
This 128GB kit contains two 64GB DDR5 6400 Registered ECC RDIMMs built for the Supermicro H14DST-F motherboard. The modules run at 1.1V with CL52 latency and a 2Rx4 organisation that matches the board's memory controller requirements. They are intended for administrators who need the full capacity the platform supports without manual tuning.
128GB capacity and registered headroom
The 2Rx4 registered design lets every slot run fully populated at the rated 6400 speed while ECC corrects single-bit errors on the fly. This configuration handles large virtualisation workloads, in-memory databases and multi-tenant containers where silent data corruption cannot be tolerated. The kit reaches its limit when the platform's maximum DIMM count or total memory ceiling is reached, which varies by CPU and BIOS revision.
Replaces slower or smaller DDR5 RDIMMs
The upgrade is worthwhile when existing modules run below 6400, lack ECC, or leave slots empty because of rank or voltage mismatches. Swapping to this spec-matched kit restores full-channel bandwidth and eliminates the population restrictions that forced partial fills. It is not for systems that require UDIMM or SODIMM form factors, nor for boards limited to lower DDR5 speeds or different pin counts.

Questions about this item
Will the 288-pin DDR5 6400 RDIMM kit run at rated speed on a Supermicro H14DST-F already populated with older DDR5 modules?
The kit is spec-matched to the H14DST-F memory controller; mixed-rank or mixed-speed DIMMs may force the channel down to the slowest common JEDEC profile.
How can I confirm the 128 GB 2Rx4 ECC RDIMM kit is operating at CL52 and 1.10 V after installation?
Enter the BIOS or use a tool such as dmidecode to verify speed shows 6400 MT/s, CAS latency 52, voltage 1.10 V, and ECC status enabled.
Does the package include only the two 64 GB RDIMMs or are heat spreaders and installation hardware also supplied?
The box contains the two 64 GB DDR5 6400 RDIMM modules; no heat spreaders or extra mounting hardware are included.
